[Ville Vainio] <vivainio-AT-gmail.com>: Ville has made many improvements
to the core of IPython and was the maintainer of the main IPython
trunk from version 0.7.1 to 0.8.4.

[Gael Varoquaux] <gael.varoquaux-AT-normalesup.org>: work on the merged
architecture for the interpreter as of version 0.9, implementing a new WX GUI
based on this system.

[Barry Wark] <barrywark-AT-gmail.com>: implementing a new Cocoa GUI, as well
as work on the new interpreter architecture and Twisted support.

[Laurent Dufrechou] <laurent.dufrechou-AT-gmail.com>: development of the WX
GUI support.

[Jörgen Stenarson] <jorgen.stenarson-AT-bostream.nu>: maintainer of the
PyReadline project, necessary for IPython under windows.

The IPython project is also very grateful to:

Bill Bumgarner <bbum-AT-friday.com>: for providing the DPyGetOpt module
which gives very powerful and convenient handling of command-line
options (light years ahead of what Python 2.1.1’s getopt module does).

Ka-Ping Yee <ping-AT-lfw.org>: for providing the Itpl module for
convenient and powerful string interpolation with a much nicer syntax
than formatting through the ‘%’ operator.

Arnd Baecker <baecker-AT-physik.tu-dresden.de>: for his many very useful
suggestions and comments, and lots of help with testing and
documentation checking. Many of IPython’s newer features are a result of
discussions with him (bugs are still my fault, not his).

Obviously Guido van Rossum and the whole Python development team, that
goes without saying.

And last but not least, all the kind IPython users who have emailed new code,
bug reports, fixes, comments and ideas. A brief list follows, please let us
know if we have ommitted your name by accident:

Dan Milstein <danmil-AT-comcast.net>. A bold refactoring of the
core prefilter stuff in the IPython interpreter.

[Jack Moffit] <jack-AT-xiph.org> Bug fixes, including the infamous
color problem. This bug alone caused many lost hours and
frustration, many thanks to him for the fix. I’ve always been a
fan of Ogg & friends, now I have one more reason to like these folks.
Jack is also contributing with Debian packaging and many other
things.
